In my work I have presented the hydrophilic interaction liquid chromatography as
a technique for the separation and analysis of N-glycans. N-glycans and glycans in general are an important group of compounds in biological systems. They are involved in a variety of different biological processes that are needed for the noraml function of our body. They are also very interesting for the pharmaceutical industry, as they play a crucial role in the development of new biopharmaceuticals and can be used as biomarkers for different kinds of disease. In my work I have described glycans, their structure and explained what makes them such an analytical challenge. I have presented hydrophilic interaction chromatography, how it works and its mechanism of separation and the diffrent mobile and stationary phases it uses. I explained what makes it such a good technique for the separation of polar and hydrophilic compounds and presented a couple of examples of the use of HILIC for the separation of Nglycans. At the end I have outlined a HILIC-HPLC-FL method for the analysis of 2-AB labeled N-glycans.
